retired construction superintendent. i have a home made 12x24 cnc, and 1 each of the 3020-3040-6040 cncs. I also have a intelicarve. i acquired most on craigslist for next to nothing from various people who could not get them to run correctly, and tore them apart and couldn’t put them back together. have most up and running. Started out as a project for myself and grand kids, and has lead into local neighborhood kids joining in. Its really great to see the younger generation take an interest in woodworking, as i have complete woodworking shop, and now getting them involved in cnc work, They range from 6-18 years of age. What a joy it give me to see the interest.
